Once I was talking to this girl from NY about sliding, and she said, what, we call it sledding. Not really an interesting conversation, but I thought it was kinda funny.
Also, the Slip 'N' Slide is something I always wanted to try as a kid and never had the chance. I can still remember the song from the TV commercial. As an adult, it seems to me to be the most dangerous and painful looking activity that children participate in. Do they still sell those death mats?
